how to fix ionic application error when we serve the application - ionic-framework

When we run this command (ionic lab) then it show this error.
how we solve it..
ng run app:serve --host=0.0.0.0 --port=8100
[ng] The run command requires to be run in an Angular project, but a project definition could not be found.
[ERROR] ng has unexpectedly closed (exit code 1).
The Ionic CLI will exit. Please check any output above for error details.

check the command line if you are in the directory containing package.json and run the following commands:
npm install
ionic serve

It seems you are not inside the right folder. You have to run your ng run command in the same place your runned your ng new command (or wherever you have initialized your Angular project).

Do you have the last version of the angular cli?
npm install -g #angular/cli
It might also be useful to post the log
I have spent several hours to fix this .Hope it will help someone
Kindly follow the below steps:
find your npm path from the environmental variable. And copy that path and paste it in notepad
2.Go to control panel ->uninstall the node js
3.after uninstalling,restart the system.
4.Now go to npm path in file explorer.
5.And delete the folder named npm and npm-cache
6.And now install the node(LTS version) and angular(refer from the below link for step by step installation)
https://www.zeolearn.com/magazine/setup-angular-windows
note:Dont run the cmd as administrator.Unless ,the installation fails
7.Once you verified that angular is running fine using ng serve -o
8.Install the ionic by npm install -g ionic#latest
9.And run ionic serve.
10.Hope it helps.Happy coding :)

Unable to debug React Native using VSCode

Fresh init of a RN project with a fresh copy of React Native Full Pack in VSCode. I'm unable to get this new project to debug, but am able to get other projects to debug using the same methods. I've tried recreating the project and still no dice. I can use react-native run-android in a command prompt to get it to debug, but not VSCode. I keep getting this error:
events.js:167
throw er; // Unhandled 'error' event

I've also tried running the packager first, but it still default to a --no-packager run.
Deleting and reinstall NPM packages seems to work some of the time. But a better way to fix this problem is to run gradlew.bat clean from inside the android folder of the RN directory, then rerun the packager and restart the app.
install NodeWatcher.
use this command in windows : npm install node-watch
also try this.
You can also clean your build cache and gradle cache.
